We currently have 10 sizes in our range, as well as 2 designs in the prototype stage.
Our first muzzles launched after our Kickstarter, these were sizes Tolly, Neli and Sunny, followed by the size Rex a few months later.
Size Tolly
Size Neli
Size Sunny
Size Rex
Whilst we are still incredibly proud of our original sizes, seeing the muzzles on thousands of dogs meant that we have learned things along the way and found improvements we can make to ensure future muzzles are even better.
No one has designed or manufactured muzzles like this before, so the entire process has been a learning curve, for everyone involved.
Our next size to launch was the eagerly anticipated size Harry. This was a completely different shape to the muzzles we have made before, as it is short and wide, aimed at Bully type dogs. We worked really hard ensuring that that edges were much rounder on this muzzle (which sounds easy but, in the injection-moulding world – not so much!) and was therefore softer on the dog.
Size Harry
One of our customers also reached out to us to tell us that she had turned a head strap into a chin strap on her dog’s Harry muzzle, to help keep it stable as he was at the lower end of the recommended measurements for Harry.
We loved the idea and made chin straps an addition to our additional strapping collection.
(Thank you so much Aimee!)
We also introduced a new padded noseband add-on.
Biothane is generally quite soft on dogs but some dogs who perhaps have less fur on the nose or are more sensitive, needed something more to ensure the muzzle wasn’t rubbing. The padded noseband had a squishy layer of foam on the inside to make it even more comfortable!
Next, size Taz launches which again has the softer edges to make it a smoother muzzle.
We also increased the pant space even more to make sure dogs with a long jaw could pant freely. We learned from our previous designs that the top profile of the muzzle could obstruct the vision for some face shapes, so we really flattened the top in front of the eyes to limit this a much as possible.
We also redesigned the way the head strap attaches, so that instead of the strap folding around the basket and creating a bump that could potentially rub some sensitive dogs, the strap now screws directly onto the basket so the noseband can lay nice and flat on the dogs’ face.
Size Taz
Our next release wasn’t actually a muzzle but was another new add-on for our existing muzzles! Whilst we love the treat hole that we designed in the front of our muzzles, we recognised that it wasn’t ideal for dogs who scavenge! So, we designed a patent-pending scavenger guard which easily clips onto the front of the muzzle to cover the treat hole and front panel.
We have 2 different scavenger guard styles now!
Standard Scavenger Guard
Extra Secure Scavenger Guard
After changing manufacturer and designer, we were able to really fine tune our design process and create a muzzle which we felt was our best yet.
Size Mitzy
The Mitzy was the next muzzle to launch, and it took a long time to perfect. Its development brought a number of hurdles and manufacturing challenges, but our commitment to creating a muzzle that prioritises comfort for the dog made every step worthwhile.
The Mitzy introduced several key design improvements, including softer edges, increased pant space, a flatter top profile, and our updated head strap design. It also features carefully considered shaping under the neck alongside the additional pant space, helping to reduce the muzzle bumping against a dog’s neck as much as possible while maintaining comfort and freedom of movement.
As our biggest muzzle to date, the Mitzy represented a major step forward in both design and manufacturing, and in 2025 it was recognised with the Pet Industry Federation Innovation Award, a proud milestone in our journey to keep improving muzzle welfare and comfort for dogs.
Size Harry 2.0
Next came the re-evaluation of our Size Harry muzzle. Due to changes in manufacturing and tooling complications, we saw an opportunity to take everything we had learned from designing our other muzzles and apply it to one of our most popular sizes. The result was the Harry 2.0, a carefully refined evolution of the original design that maintained the same trusted internal width measurements while significantly improving comfort, fit, and overall user experience.
The Harry 2.0 introduced a number of thoughtful refinements, including improved chin space beneath the treat hole to better accommodate slightly undershot jaws, slimmer and lighter bars to reduce overall weight without compromising strength, and smoother cheek-contact edges for enhanced comfort. Every internal edge was fully polished to minimise friction, while the removal of the inward “tick” on the inner cheek top corner created wider cheek room and a more comfortable fit.
We also redesigned the corners near the neck to allow easier head movement, reduced the bulk of the internal bars for a sleeker feel, and updated the head strap fastening to prevent downward pressure on the noseband. Despite all of these improvements, the internal width measurements remained unchanged, ensuring the same reliable fit dogs were already accustomed to.
The Harry 2.0 quickly became a standout product within our range, and in 2025 it was recognised with the PetQuip Product of the Year Award, another proud milestone in our mission to continually improve muzzle comfort, functionality, and welfare.
Size Pippa
We didn’t stop there. As our range continued to grow, we recognised a gap in the market for a smaller short-and-wide fit muzzle — something designed specifically for dogs with shorter snouts and broader facial structures who often struggle to find a comfortable, welfare-focused fit. By listening closely to our community and learning from every muzzle we had developed before, we set out to create the Size Pippa.
Pippa became the smallest muzzle in our Short & Wide Fit collection and the shortest basket in our range, while still maintaining safe and functional panting, drinking, and treat space. Designed by a team of animal behaviourists, every detail was carefully considered to ensure comfort, practicality, and welfare remained at the forefront.
The muzzle features carefully contoured shaping beneath the treat hole to better accommodate slightly undershot jaws, helping provide comfort even for dogs with unique facial structures. Smooth internal and cheek-contact edges help minimise rubbing and pressure points, while thinner internal bars create a lighter, sleeker feel without compromising durability or stability.
Pippa also introduced our vision-friendly flat head strap fastening, designed to reduce visual obstruction and better support a dog’s spatial awareness. As with all of our basket muzzles, it was created with ethical muzzle use in mind, ensuring dogs can pant, drink, and comfortably receive treats when fitted correctly.
The launch was incredibly well received, with pre-orders shipping on time and marking another exciting milestone in The Muzzle Movement’s journey of innovation and welfare-led design.
Size Mia & Size Jimmy Small Size Dog Muzzle
Then came our small sizes — Size Mia and Size Jimmy. Their development marked another important milestone for The Muzzle Movement, because for far too long small dogs have been overlooked when it comes to muzzle design, education, and welfare. As we explored the needs of smaller breeds more deeply, it became increasingly clear that small dogs deserve the same consideration, safety, and properly fitted equipment as larger dogs.
Small dogs are often unfairly dismissed when it comes to behavioural support, despite research showing they can experience fear, anxiety, and defensive behaviours just as much, if not more, than larger breeds. Unfortunately, the market has historically offered very limited options for smaller dogs, especially those with unique head shapes or shorter snouts.
That’s why we worked hard to develop Size Mia and Size Jimmy: muzzles specifically created for smaller dogs, with welfare, comfort, and functionality at the centre of the design process. Rather than simply scaling down larger muzzles, these sizes were carefully engineered to suit the unique anatomy and behavioural needs of smaller breeds.
Like the rest of our range, Mia and Jimmy are designed to allow dogs to pant, drink, and take treats comfortably when fitted correctly. They feature lightweight basket designs, smooth internal edges, and our welfare-focused shaping to support safer, more positive experiences for dogs and their guardians alike.
The launch of Mia and Jimmy represents something much bigger than simply adding smaller sizes to our range. It reflects our ongoing mission to challenge outdated perceptions around muzzles and advocate for all dogs, regardless of size. Because small dogs need safe, comfortable, and ethical muzzle options too. Read More

So what’s next in our Muzzle Evolution?
We have learned SO much from our first ever design to our most recent ones. We have some incredibly talented designers and manufacturers on board, and we have honed our own skills in recognising what is needed to improve on what we have already done.
We understand fit better, we know more about the confirmation of a dog’s face, we know what works and what doesn’t in terms of muzzle shape and positioning, we recognise what our customers want and need and most importantly we have taken feedback on board to make lives better for muzzled dogs.
We currently have a further two new muzzle sizes in the design process that we are working hard to bring to launch in the near future.

Size Patrick
Size Galaxy
Some are ready to go, but it costs us around £40k to manufacture the tools for just ONE size, hence why it takes us some time to build up the funds needed to reinvest.
We are unbelievably excited and incredibly proud of our future designs – one in particular has been a long process and we believe we have created a muzzle that no-one has been able to achieve before. It is beautifully shaped to ensure that special dogs wearing them are as comfortable as possible, it has been thoroughly tested on several dogs and we have designed entirely new strapping for it. It has been a labour of love to create a muzzle that is much-needed worldwide so we are very excited for its release – hopefully in 2026/7!
The tooling for each of our sizes has a lifespan too, so when each tool can no longer be used for current designs, we will tweak and alter them to create improved versions of each size.
We are all passionate perfectionists with dog welfare at the front of our minds, so we keep learning and we will ALWAYS keep doing better. For the dogs.
